The youngster joined the Arsenal youth academy at the age of 13 from Southend in 2008.

The defensive midfielder made two appearances for the Gunners during his eight years at the club and spent last season on loan with Hull in the Championship where he made 24 appearances in all competitions.

In his statement he said: “I’m so excited to sign for such a huge club like Newcastle United. I’ve heard stories from other players just what it’s like to run out onto St James’ Park in front of more than 50,000 passionate Geordies and the infamous Gallowgate. I know NUFC fans are deeply passionate and committed when it comes to their football and this club and that’s exactly what they can expect from me when I pull on the black and white stripes this season. Let’s get back to the Prem! Thanks for the warm welcome! #ToonArmy #NewHome”

Newcastle are looking to overhaul their squad which suffered relegation to the Championship last season, as they attempt to bounce back to the top flight at the first time.

The Magpies managed to keep hold of former Real Madrid boss Rafa Benitez and have already brought in five players this summer, which include Hayden, Dwight Gayle and Matt Ritchie all coming from Premier League sides.
